Abstract

PURPOSE: A kimchi refrigerator is provided to minimize noise and power consumption by reducing the driving rate of a compressor remarkably. CONSTITUTION: A kimchi refrigerator is comprised of: a cabinet having at least one couple of storerooms(3); plural evaporators(6) for cooling each storeroom; a compressor(7) for supplying refrigerant to the evaporators; temperature sensors(10) for detecting temperatures of the two storerooms; and valves arranged on refrigerant tubes toward the evaporators. To control the kimchi refrigerator, the temperature sensors measure the temperatures of each storeroom. One of the valves is opened/closed at predetermined valve opening/closing temperatures while the other valve is opened at a specific temperature lower than the valve opening temperature. The compressor is driven when at least one of the valves is opened. Therefore, the compressor is driven to the minimum to minimize noise and excess power consumption.

Description

김치냉장고 및 그 제어방법{Kimchi Refrigerator and Control Method thereof}Kimchi Refrigerator and Control Method

본 발명은, 김치냉장고 및 그 제어방법에 관한 것으로서, 보다 상세하게는, 압축기의 운전율을 현저히 감소시켜 소음을 줄이고 소비전력을 최소화할 수 있는 김치냉장고 및 그 제어방법에 관한 것이다.The present invention relates to a kimchi refrigerator and a control method thereof, and more particularly, to a kimchi refrigerator and a control method that can significantly reduce the operation rate of the compressor to reduce noise and minimize power consumption.

일반적으로 김치냉장고는, 하나 혹은 2개의 김치 저장실을 형성하는 캐비넷과, 상기 저장실의 가열을 위한 히터와 냉각을 위한 냉각시스템을 구비하고 있다. 그리고 냉각시스템은 냉매를 압축하는 압축기와, 압축된 냉매를 응축하는 응축기와, 주위 증발잠열을 이용하여 냉기를 형성하는 증발기의 폐회로로 구성된다.In general, a kimchi refrigerator includes a cabinet forming one or two kimchi storage chambers, a heater for heating the storage chambers, and a cooling system for cooling. The cooling system includes a compressor for compressing the refrigerant, a condenser for condensing the compressed refrigerant, and a closed circuit of the evaporator for forming cold air by using the latent heat of evaporation.

종래의 김치냉장고에는 하나의 김치 저장실이 구비되어 있었거나, 2개의 저장실이 구비된 경우에도 각 저장실이 개별적으로 제어되지 않았기 때문에, 저장실의 가열을 위해 히터를 제어하거나 냉각을 위하여 냉각시스템을 제어하기가 비교적 간단하였다. 그러나, 최근에는 2개의 저장실마다 독립된 증발기와 히터가 설치되어 각 저장실이 개별적으로 냉각 및 가열되도록 제어하여 하나의 저장실에서 김치를 숙성시킬 때에 나머지 저장실에서는 김치를 저장시킬 수 있도록 하고 있다. 이것은 각 저장실의 온도가 미리 설정된 냉각시스템 작동온도나 폐쇄온도에 도달하게 되면 냉각시스템을 작동시키거나 정지시키고, 또한 각 저장실의 온도가 히터 작동온도나 폐쇄온도에 도달하면 히터를 작동시키거나 정지시킴으로써 행하여지게 된다. 이러한 개별적 제어방법으로써 각 저장실을 독립적으로 냉각 혹은 가열시킬 수 있다.In the conventional kimchi refrigerator, one kimchi storage compartment is provided, or even when two storage compartments are provided, each storage compartment is not individually controlled. Thus, to control the heater for heating the storage compartment or to control the cooling system for cooling. Was relatively simple. Recently, however, independent evaporators and heaters are installed in each of the two storage compartments to control each storage compartment to be individually cooled and heated so that the kimchi can be stored in the remaining storage compartments when the kimchi is matured in one storage compartment. This enables the cooling system to be turned on or off when the temperature of each storage room reaches a preset cooling system operating or closing temperature, and also activates or stops the heater when the temperature of each storage room reaches the heater operating or closing temperature. Will be done. This individual control method allows each reservoir to be cooled or heated independently.

그런데, 이러한 종래의 김치 냉장고의 개별적 제어방법에 있어서는, 만약 각 저장실이 모두 저장모드이고, 상호 교차적으로 냉각되어야 하는 경우가 발생하면, 하나의 저장실 냉각을 수행하였던 압축기는 다른 하나의 저장실 냉각을 위해 다시 작동되어야 하기 때문에 항상 운전 상태에 놓이게 된다. 이로써 압축기 운전율은 높아져 소비전력이 과다해지고 압축기 작동에 의한 소음이 계속되는 문제점이 있다.However, in the individual control method of the conventional kimchi refrigerator, if each storage room is all storage mode, and if it needs to cross cool each other, the compressor that performed the cooling of one storage compartment is to cool the other storage compartment. It is always in operation because it must be operated again. As a result, the operation rate of the compressor is increased, the power consumption is excessive, and there is a problem in that noise due to compressor operation is continued.

따라서, 본 발명의 목적은, 압축기의 운전율이 현저히 감소되어 소음 및 소비전력을 최소화할 수 있는 김치냉장고 및 그 제어방법을 제공하는 것이다.Accordingly, an object of the present invention is to provide a kimchi refrigerator and a control method thereof which can significantly reduce the operation rate of the compressor and minimize noise and power consumption.

이하에서는 첨부도면을 참조하여 본 발명에 대해 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도1은 본 발명에 따른 김치냉장고의 사시도이고, 도2는 도1의 종단면도이다. 이들 도면에 도시된 바와 같이, 본 발명에 따른 김치냉장고는 상향 개방된 투입개구를 갖는 본체(1)와, 본체(1)의 투입개구를 개폐하도록 본체(1)의 상면 일측을 중심으로 회동하는 도어(2)와, 김치 및 그 밖의 종류의 음식물 등의 저장용기를 분리수용할 수 있는 복수의 저장실(3)과, 본체(1)의 상부 전면에는 저장실(3) 내에 수용된 음식물의 종류 및 음식물의 숙성시간, 온도조건 등을 선택하는 다수의 조작버튼(4)을 구비한 조작패널(5)과, 각 저장실(3)을 냉각시키는 증발기(6)와, 냉매를 압축하는 압축기(7)와, 압축된 냉매를 응축하는 응축기(8)와, 각 저장실을 가열시키는 히터(9)와, 각 저장실(3) 내의 온도를 감지하는 온도감지센서(10)와, 다수의 기기 부품을 수용하는 기기부품실(11)을 갖는다.1 is a perspective view of a kimchi refrigerator according to the present invention, Figure 2 is a longitudinal cross-sectional view of FIG. As shown in these drawings, the kimchi refrigerator according to the present invention is rotated about the main body 1 having an upwardly open input opening and one side of the upper surface of the main body 1 to open and close the input opening of the main body 1. The door 2, a plurality of storage chambers 3 capable of separating and storing storage containers such as kimchi and other kinds of foods, and types and foods of foods contained in the storage chambers 3 in the upper front of the main body 1 An operating panel 5 having a plurality of operation buttons 4 for selecting a ripening time, temperature conditions, and the like, an evaporator 6 for cooling each storage chamber 3, a compressor 7 for compressing a refrigerant, A condenser (8) for condensing the compressed refrigerant, a heater (9) for heating each storage compartment, a temperature sensor (10) for sensing a temperature in each storage compartment (3), and a device for accommodating a plurality of components The component chamber 11 is provided.

도 3은 본 발명에 따른 김치냉장고 냉각 사이클도로서, 이에 도시된 바와 같이, 압축기(7)에 의해 압축된 냉매가 응축기(8)에서 응축되고, 응축된 냉매는 드라이어(13)와, 증발기(6)를 향한 냉매 배관에 배치된 밸브(14,15)의 개·폐에 의하여 증발기(6)로 유입되어 각 저장실을 냉각시키게 된다.3 is a kimchi refrigerator cooling cycle according to the present invention, as shown in this, the refrigerant compressed by the compressor 7 is condensed in the condenser 8, the condensed refrigerant is a dryer 13, the evaporator ( 6 is introduced into the evaporator 6 by the opening and closing of the valves 14 and 15 arranged in the refrigerant pipe facing 6) to cool the respective storage chambers.

도 4는 본 발명에 따른 김치냉장고 제어 블록도로서, 제어부(18)는, 김치의 숙성 및 저장을 위하여 선택되는 김치숙성모드 선택부(17)와 저장실 온도감지센서로부터 입력된 신호에 기초하여 저장실 가열을 위한 히터(9)와 냉각을 위한 압축기(7)를 제어한다. 또한 제어부(18)는 미리 설정된 밸브개방온도 및 밸브폐쇄온도에 따라 밸브(14,15)의 개·폐를 제어하여 냉각이 필요한 저장실을 냉각시킨다. 즉, 좌(우)측 실내만 개방온도에 도달한 경우에는 좌(우)측 실내의 증발기를 향한 냉매 배관에 배치된 밸브만 개방시킨다.4 is a block diagram of a kimchi refrigerator control according to the present invention, wherein the control unit 18 is based on a signal input from a kimchi ripening mode selection unit 17 and a storage room temperature sensor selected for ripening and storing kimchi. The heater 9 for heating and the compressor 7 for cooling are controlled. In addition, the control unit 18 controls the opening and closing of the valves 14 and 15 in accordance with the preset valve opening temperature and the valve closing temperature to cool the storage chamber requiring cooling. That is, when only the left (right) room reaches the opening temperature, only the valve disposed in the refrigerant pipe for the evaporator of the left (right) room is opened.

그런데 만약 두 저장실 모두 저장 모드인 경우에 있어서, 좌(우)측 실내가 개방온도에 도달한 때에 우(좌)측 실내가 폐쇄온도에 도달하고, 우(좌)측 실내가 개방온도에 도달한 때에 좌(우)측 실내가 폐쇄온도에 도달하는 주기를 가진 냉각 사이클이 발생한다면 상기 압축기(7)는 항상 운전 중에 있어야 한다. 따라서 이와 같이 압축기(7)에 무리를 주는 상황이 발생하지 않도록, 제어부(18)는 상기 두 밸브(14,15)가 상호연동관계를 가지면서 개·폐되도록 제어한다.However, if both storage compartments are in storage mode, when the left (right) room reaches the opening temperature, the right (left) room reaches the closing temperature, and the right (left) room reaches the opening temperature. The compressor 7 must always be in operation if a cooling cycle occurs with a period in which the left (right) room reaches the closing temperature at that time. Therefore, the control unit 18 controls the two valves 14 and 15 to be opened and closed while having a mutually interlocking relationship so that the situation in which the compressor 7 is not overwhelmed.

도 6은 본 발명에 따른 김치냉장고 제어 흐름도로서, 도 5의 본 발명에 따른 김치냉장고 제어 파형의 일 예의 b-e 구간의 제어 과정에 대한 제어 흐름도를 나타낸 것이다. 이 제어흐름도는 제어 과정을 쉽게 설명하기 위하여, 저장실이 두 개이고 두 저장실이 모두 저장 모드 상태인 경우, 밸브개방온도 이하의 소정의 유지온도가 밸브폐쇄온도와 동일한 경우 및 각 저장실의 밸브개방온도와 밸브폐쇄온도가 동일한 경우를 가정한 것이다. 또한, 현재 b 상태는 좌실 내 밸브가 개방상태이고 압축기가 운전 중인 상태이므로 현 상태에서 우실 내의 온도가 개방온도에 도달하여 우실 내 밸브가 개방되는(S1~S2) 시점부터 본 제어방법이 적용된다고 가정하고 도 5 및 도 6을 참조하여 설명하면, 이 후 압축기가 운전중이고 우실 내 밸브가 개방상태가 되므로, 좌실 내의 온도가 폐쇄온도 이하인 경우 당연히 좌실 내 밸브가 차단되지만, 폐쇄온도 이상이 되면 좌실 내 밸브가 개방되어 이미 운전 중인 압축기와 응축기를 통과한 냉매를 좌실 내의 증발기로 유입시킨다(S3~S5). 그리고 우실 내 온도가 폐쇄온도에 도달하면 압축기를 중지시키고 우실 내 밸브를 폐쇄시킨다(S6~S8).FIG. 6 is a flow chart illustrating a Kimchi refrigerator control according to the present invention, and shows a control flowchart of a control process of a b-e section of an example of the Kimchi refrigerator control waveform according to the present invention of FIG. 5. This control flow chart is used to explain the control process easily, when two storage chambers and both storage chambers are in storage mode, when the predetermined holding temperature below the valve opening temperature is equal to the valve closing temperature and the valve opening temperature of each storage chamber. It is assumed that the valve closing temperature is the same. In addition, since the current state of b is the valve in the left chamber is open and the compressor is in operation, the control method is applied from the time when the temperature in the right chamber reaches the opening temperature and the valve in the right chamber is opened (S1 to S2). 5 and 6, since the compressor is in operation and the valve in the right chamber is opened, the valve in the left chamber is naturally shut off when the temperature in the left chamber is below the closed temperature. The inner valve is opened to introduce the refrigerant that has already passed through the compressor and the condenser into the evaporator in the left chamber (S3 ~ S5). When the temperature in the right chamber reaches the closing temperature, the compressor is stopped and the valve in the right chamber is closed (S6 to S8).

계속해서, 이번에는 좌실 내의 온도가 개방온도에 도달하면 압축기를 작동시키고 좌실 내 밸브를 개방한다(S9~S11). 이 후, 압축기가 운전 중이고 이번에는 좌실 내 밸브가 개방상태이므로, 우실 내의 온도가 폐쇄온도 이하인 경우 당연히 우실 내 밸브가 차단되지만 폐쇄온도 이상이 되면 우실 내 밸브가 개방되어 이미 운전 중인 압축기와 응축기를 통과한 냉매를 우실 내의 증발기(5)로 유입시킨다(S12~S14). 그리고 좌실 내 온도가 폐쇄온도에 도달하면 압축기 운전을 중지시키고 좌실 내 밸브를 폐쇄시킨다(S6~S8).Subsequently, this time, when the temperature in the left chamber reaches the opening temperature, the compressor is operated and the valve in the left chamber is opened (S9 to S11). After that, since the compressor is in operation and the valve in the left chamber is open at this time, if the temperature in the right chamber is below the closing temperature, the valve in the right chamber is of course shut off, but when the temperature is above the closing temperature, the valve in the chamber is opened to open the compressor and the condenser. The refrigerant passing through is introduced into the evaporator 5 in the right chamber (S12 to S14). When the temperature in the left compartment reaches the closed temperature, the compressor operation is stopped and the valve in the left compartment is closed (S6 to S8).

이상과 같은 제어방법에 의하여, 상기 두 밸브가 상호연동관계를 가지면서 개·폐되어 압축기의 운전율이 현저히 낮아지며 따라서 소음 및 소비전력을 최소화할 수 있다.By the above control method, the two valves are opened and closed while having an interlocking relationship, and thus the operation rate of the compressor is significantly lowered, thereby minimizing noise and power consumption.

전술 및 도시한 실시 예에서는, 저장실이 2개였으나 복수의 저장실이라도 무방하며, 2개의 저장실이 모두 저장 모드인 경우가 상술되었으나 2개의 저장실이 모두 저장 모드가 아니어도 저장실 모두 냉각이 필요한 경우에도 실시 가능함은 물론이다. 또한, 각 저장실의 밸브개방온도와 밸브폐쇄온도가 동일한 경우와 밸브개방온도 이하의 소정의 유지온도가 밸브폐쇄온도와 동일한 경우에 대하여 상술하였으나, 각 저장실마다 밸브개방온도와 밸브폐쇄온도를 달리 설정하여 실시할 수도 있고 밸브개방온도 이하의 소정의 유지온도를 밸브폐쇄온도와 달리 설정하여 실시할 수도 있다. 그리고 압축기와 응축기가 모두 하나로 구성된 냉각사이클에 대하여 상술되었으나 압축기만 공유한 경우에도 밸브 설치 위치를 변경하여 동일하게 실시할 수 있다.In the above-described and illustrated embodiments, although there are two storage compartments, a plurality of storage compartments may be used, and the two storage compartments are both in the storage mode, but the two storage compartments may be implemented even when both storage compartments require cooling even when the storage modes are not in the storage mode. Of course. In addition, the case where the valve opening temperature and the valve closing temperature of each storage chamber are the same and a predetermined holding temperature below the valve opening temperature are the same as the valve closing temperature are described above. However, the valve opening temperature and the valve closing temperature are set differently for each storage chamber. It may be carried out by setting the predetermined holding temperature below the valve opening temperature different from the valve closing temperature. And although the above-described cooling cycle consisting of a compressor and a condenser all in one, even if only the compressor can be shared by changing the valve installation position.

이상 설명한 바와 같이, 본 발명에 따르면, 압축기의 운전율을 현저히 감소시켜 소음 및 과다소비전력을 최소화할 수 있는 김치냉장고 및 그 제어방법이 제공된다.As described above, according to the present invention, there is provided a kimchi refrigerator and a control method thereof that can significantly reduce the operation rate of the compressor to minimize noise and excessive power consumption.
